Hi
2 problems:
* unresponsive system
* BUG
I've been ripping some audio CDs recently under 2.6.26 and sometimes, I assume
when there have been imperfections/retries etc, the system has become
unresponsive - 10s of seconds for mouse movement, keystrokes to respond.
This resulted in many
kernel: ide: failed opcode was: unknown
kernel: hda: drive not ready for command
kernel: hda: status timeout: status=0xff { Busy }
top reported very high %si (>95%)
and when I tried (*something*) to recover using:
hdparm -w /dev/hda
hdparm -w /dev/hdb
I got a BUG.
I know it says 'dangerous' - so if the reply is "so don't do that then" I shall
respect it :)
OTOH this may be unexpected so I'm reporting it.
All my drives are on sata channels, I just have a Plextor CDRW and a DVDRW on
the ide channel.
One additional comment, when the CD drive gets into this state, it persists
after a hibernate, cold boot and restore. It is fine after a cold reboot.
This suggests to me that the problem may be in the kernel/driver.
Let me know what else I can provide to help.
In the meantime I'll be trying 2.6.27-rc?
